WINDOW CONTROLLER AND LOCK SPECIFICATION forming part of Letters Patent N 0. 769,007, dated lAugust 30, 1904.

Application filed April 14, 1904.

To @ZZ 71,171,077?, it may concern,.-

Be it known that ,L GEORGE MoDowELL, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State ofv New York, have invented a new and Improved iVindow Controller and Lock, of which the following' is a full, clear, and exact description.

My invention relates to a loclr for windows adapted to hold thesashes of a window-frame in adjusted relation to each other.

The purpose of the invention is to provide a device of the character above mentioned which is adapted for attachment to the meeting-rail of the lower sash, for example, and for frictional binding and locking engagement.

with a side rail of the upper sash, so that two sashes may be locked together, though opened at the top and bottom to any desired extent; and a further purpose of the invention is to so construct the device that either sash may be independently operated when desired and so that, further, when the two sashes have been closed in the window-frame the device will automatically act to lock and secure the sashes in their closed position.

The invention consists in the novel constr uction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a portion of a window-frame and a portion of an upper and a lower sash and a perspective view. of the device applied, the device being attached to the lower sash and in frictional engagement only with the upper sash. Fig. 2 is a Avertical section through the meeting-rails of the upper and lower sashes of a window-frame and a side elevation of the device, the device being shown both in frictional engagement with the I upper sash and in locking engagement therewith. Fig. 3 is a horizontal section taken ,practically on the line 3 3 of Fig. 2.- Fig. 4

modification in the construction of the locking device, and Fig. 6 is a front sectional elevasists of a body comprising an inner vertical section 10, having a slot 10 therein in the interest of lightness, and an outer section l2,

which is also slotted, so as to render the body of the device as light as possible, and the said forward section12 is given a downward and inward inclination from a point near its upper end to a point near its lower end. The outer inclined face of the body-section 12 is provided with teeth 18, as is clearly shown in Fig. 1. At the upper portion of the body of the device D a pocket 11 is formed, which pocket is more or less concave, as is shown in Fig. 1, and is adapted for a purpose to be hereinafter described.

Eyes 14 are produced upon the sides of the said body of the device near its upper portion, and the ends of a bail 17 are carried through these eyes, (shown best in Figs. 1 and 4,) and the extremities of the bail are enlarged to prevent withdrawal. This bail at its forward or outer ends serves to journal a controlling' device which is in the nature of two opposing the device, as is shown in Figs. 1 and 4. The

`teeth of the pinions are thus staggered in under all adjustments thereof until purposely' removed, which is accomplished by carrying the friction-Wheel upwardand inward, and if IOO the friction-wheel is not to be used at all the controlling device is seated in the pocket 11 at the top of the body of the main device, as is illust-rated by dotted lines in Fig. 2, so that it will be observed the controlling device may be carried into or carried out of action whenever desired, and when in action the frictional engagement between the wheel 18 and the opposing surface of the upper sash will keep the two sashes in firm engagement, so that one sash cannot be moved without moving the other.

It is very desirable that the upper and lower sashes when closed shall be locked in their closed position and that the said locking shall be automatically accomplished. To that end I employ a bolt 19, which under the construetion shown in Figs. 1, 2, and 3 is provided with a suitable head of any desired shape to be engaged by the fingers of a hand and an opposite beveled end. This beveled end is adapted to enter a keeper 20, which is secured to the upper sash at its bottom portion, and when the two sashes have been fully closed the said bolt will enter thel said keeper and will hold the two sashes locked until the bolt is purposely shifted.

Under the construction shown in Figs. 1, 2, and 3 the bolt 19 is guided in suitable guideways at one side of the body of the device. The inner guideway for the said bolt is designated by the numeral 20, as when the bolt is drawn outward so as to carry its beveled end out of the path of the keeper 20 a wall of a slot 21, produced in the bottom portion of the bolt, will engage with the bottom portion of the openingin the outer guide-section for the bolt, and thus hold the bolt in an outer position, as is shown by dotted lines in Fig. 2, enabling' the sashes to be operated one independent of the other and as independently as though the device were not applied; but the bolt is normally forced outward,or in position to enter the keeper 20a, by means of a spring 21a, (shown best in Fig. 3,) which engages with the forward portion of the body of the device and with the end portion of the latch or bolt 19, preferably adjacent to the recess 21 therein. Thus it will be observed that after the upper and lower sashes have been adjusted as desired and the friction wheel 18 is carried downward, so that the pinions connected with the said wheel engage with the teeth on the forward edge of the body of the device, the said friction-wheel will hold the two sashes in their adjusted relation, and when the sashes are to be closed the friction-wheel is thrown upward to the position shown in Fig. 2 or ont of engagement with the upper sash, and as soon as the upper and lower sashes have been brought to their normally closed position the bolt 1.9 will be forced into the keeper 2Ou by the spring 21a.

In Figs. 5 and 6 I have illustrated a slight departure in the construction of the lockingveaoov bolt, which bolt (shown in Figs. 5 and 6) is designated as 22 and is the ordinary round bolt adapted to enter a keeper and is con'n trolled by a spring 23 in such manner as to normally force one end of the bolt in a direction to enter the said keeper; but the bolt 22 differs from the ordinary bolt to the extent that an arm 24C is carried outward from the head portion of the bolt, and a trip-bracket 25 is secured to the side of the window-frame adjacent to which the device is located. Furthermore, where the bolt passes through the forward portion of the body D of the device a keyhole-slot 22" is produced, and in the formation of the bolt 22 a feather 22a is formed on the bolt near its handle portion, so that when the bolt is drawn outward and away from its keeper, so as to permit the sashes to be independently operated, the feather 22 will be carried out from the keyhole-slot 22", and the bolt may then be turned, so as to cause the inner end ofthe feather to engage with the outer face of the device, and thus hold the bolt from locking connection with its keeper. When the bolt is in this latter position, the arm from the bolt will be above the trip-bracket 25, and in the event that the lower sash is closed the arm 24 will be brought in engagement with the trip-bracket 25, and the bolt will then be brought into such position that it will automatically engage with said keeper, and the feather 22 will enter the said keyhole-slot 22].

It will be observed that this device is exceedinglysimple. It can be applied to any window and eectively and conveniently ernployed to hold the window-sashes locked in any desired position, and it will automatically lock the window-sashes in closed position when the upper sash has been carried upward to the extent of its range and the lower sash downward to close the window.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a window-controlling device, a bodysection adapted for attachment to the meeting-rail of a window-sash, a friction-wheel, a swinging support for the said wheel, which support is sustained by the said body, pinions carried by and acting in conjunction with the said wheel, and supported inclined surfaces on the said body, each surface being arranged for engagement with a pinion.

2. In a window controlling and locking device, a body-section adapted for attachment to a meeting-rail of awindow-sash, a frictionwheel adjustably carried by the said .bodysection, pinions carried by the said wheel, an inclined toothed surface on the said body for engagement with the said pinions, the teeth of one pinion being opposite the spaces between the teeth of the opposing pinion, and a locking-bolt carried by the said body-section at a point below the friction-wheel and pinions, as described.
